2. you throw a softball straight up into the air at a velocity of 30 feet per second. you release the softball at a height of 5.8 feet and catch it when it falls back to a height of 6.2 feet. use the position equation to write a mathematical model for the height of the softball

Step-by-step explanation:

We are given that

Initial velocity=30 ft/s

Initial position=

We have to write a mathematical model for height of the softball by using the position equation

The position equation on Earth's surface is given by

Where Initial velocity

=Initial position

Substitute the values in the equation then, we get

Hence, the mathematical model for height of the softball is given by

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
